This water will then collect will 7 above the cap 27 and will float the float 30 and-said float will move upwardly until the valve seat 34 thereon engages the tapered portion 33' which will prevent passage out through the passage 22. The waterwhich will continue to flow into the chamber 18 will i then raise around the cup-shaped float until the upper edge thereof is reached at which time it will flow intothe cup and when a predetermined amount of water has passed thereinto the cup-shaped float 30- "will fall back upon the seat 32 and, therefore, the water contained therein will beginto rise in the passage 22. Assoon as the water passage 22 begins to flow through the passage 23a siphoning effect will take place'which will draw'water from the float 30 and when the water has been withdrawn therefrom so that the quantity therein is reducedit is apparent that the water surrounding this cup-shaped float willagain cause the same to floatwhich will reengage the seat with I the tapered portion 33 which will prevent passage throughthe passage22 and thus interrupt the siphoning action and the hereinbefore described cycle of operation. will again be repeated. It isapparent from the fore- 7 going description that a very effectivewater seal is established which will prevent steam escapement but the arrangement is such that entrapped waterwill bejvery effectively discharge V g It is apparent from the foregoing description 'that the device is arranged in a manner which will'very effectively carry out its purpose. Further, since the cap 27 is arranged at the lower end of the device it is apparent that the cleaning thereof is facilitated i,

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit ofthe invention. I, therefore, do not wish to be limited to the precise detailsof construction set forth, but desire to availrnyself of such variations and modifications a'scome within the scope of the a V pended claim. 1

In a device of the class described, a housing providing a chamber interiorly thereof, aboss onsaid housing projecting downwardly into said chamber froin'the upper end-thereof, said boss having atapered end portion terminating in spaced relationship with the lower endof saidchamber and having an outlet passage extending therethrough,

ment, whereby water of condensation entering said inletopassage will raise said float until the tapered bottom portion thereof engages the tapered end portion of said boss to prevent said water escaping through said outletpassage, and when the water in said chamber reaches the height of said float said float will be lowered onto said seat thereby causing a siphoning action in said outlet passage and permitting water to'fiow from said cup therethrough.
